Seedance 30-Second One-Take Story

30 seconds, 16:9, one continuous shot with no cuts. A [lighthouse keeper] at [a storm-battered lighthouse at dusk] [climbs the stairs to relight the lamp before a ship passes], cinematic realism, the camera following in a single long take.

0-6 seconds: Wide shot from outside. Rain lashes the tower; the keeper pushes the heavy door open against the wind. The camera slowly pushes in toward the doorway.
6-14 seconds: The camera follows the keeper up the spiral stairs from behind, handheld but steady. Their lantern swings and throws moving shadows on the stone walls.
14-22 seconds: At the top, medium shot. The keeper strikes a match, shields it with one hand, and the lamp catches. The camera orbits slowly around them as the light grows.
22-30 seconds: The camera pulls back through the window and rises to a high wide shot. The beam sweeps across the sea and lights up a small ship turning away from the rocks.

Look: cold blue storm light outside, warm orange lamplight inside, visible rain, film grain.
Sound: wind and rain throughout, footsteps on stone, the match striking, a low foghorn at the end. No music, no dialogue, no subtitles.
Keep the keeper's face, coat and lantern the same from start to finish.
